Snakelocks anemone
The snakelocks anemone (''Anemonia viridis'') is a sea anemone found in the eastern Atlantic Ocean to the Mediterranean Sea.
The tentacles of anemones in deep or murky water can be a grey colour, but are otherwise usually a deep green colour with purple tips due to the presence of symbiotic algae within the tentacles that use sunlight as an energy source. Since the anemones benefit from this. they prefer brightly lit shallow waters. On average the snakelock anemone is 8 cm wide.
==Reproduction==
Unlike other cnidarians, anemones (and other Anthozoa) entirely lack the free-swimming medusa stage of the life cycle; the polyp produces eggs and sperm, and the fertilized egg develops into a planula that develops directly into another polyp.
